Hey. I can tell this is really, really hard for you. I completely understand why you're afraid of going to anybody else. Right now I imagine you feel completely stuck and alone in the world. You're not.

Don't feel bad for having been afraid. What you're going through is incredibly difficult, but others have gone through it before and come out stronger. It's okay to cry.

Try to find a teacher, librarian, or school administrator you can trust, and talk to them, even if it's not "your" teacher, even if it's a teacher you had years ago, or even if it's a teacher you don't know. You can tell them as much or as little about what you're going through as you're comfortable with, and they should be able to help you, both by just being somebody to listen, and somebody who can help you find people who can help you further.

Right now, nobody is going to be mad at you for anything you did "wrong". You aren't guilty here; somebody did something terrible to you, and it's rough, but I'm certain that there are people around you who live to help out kids like you who are going through hard times.

You don't have to stand up, or be proud, or face your friends right now. You just need one person who can help you in your crisis. Don't worry about getting in trouble—just find somebody you can trust and ask.

Stay strong. It's a cliché, but it really does get better.

EDITED TO ADD one more incredibly important thing:

It's not your fault. Don't let anybody try to convince you that it is.
